2) Natural Resources Canada makes digital topo data available at no charge
- news from CMI update May 29, 2007. (www.cmiae.org)
Users of digital topographic data will no longer have to pay to use digital versions of government maps and data. The new no-fee access policy applies to data that is solely owned by NRCan. This policy builds on an earlier initiative (http://www.geobase.ca/), which in 2003 provided free access to various co-owned federal, provincial, and territorial topographic data. As well as waiving access fees, NRCan is lifting all cost and licence restrictions on the redistribution of the data. This will help ensure that accurate and consistent information is available for users. The data collections will be made available through the GeoGratis Web portal (http://www.geogratis.gc.ca). Users will need to have a geographic information system or image analysis system and the graphics applications of editing software to view the data. This includes scanned, geo-referenced topo maps as well as the raw digital data.
Any chance CT could use some sort of web-based application to allow members to access and view the data through a browser, instead of through GIS software?

Working on something as we speak to start leveraging all this great data.  |

| I think there was a thread about this two months ago when the files were released to the public. The files were made public on April 1st (no fooling). The free NTS data is far inferior to the TRIM data seen on the BC gov. sites. |

Yeah, but CT covers Alberta, the Yukon, the East etc as well as BC.
I wish there was as good a web-based map browser for, say, the Yukon as there is for BC through the BC basemap. |

There are a few Yukon maps here http://www.geology.gov.yk.ca/gallery/index.html
but the best topographic base data is 1:50,000 NTS. The Placer map isn't bad once you've turned off the imagery. Unfortunately the only coordinate system it displays is Yukon Albers, which is essentially useless for field navigation.
The Yukon never had a program similar to the BC TRIM project, most likely because the forestry companies (who paid for a significant portion of BC TRIM) have much less of a presence there.

Stay tuned. We've thought about this too.  |

The data might be inferior, but the actual maps are (in my opinion) far superior and easier to use than anything you can make using the BC government supplied online tools. With the NTS 1:50k topo scans I can just download the mapsheet I want, crop out an area of interest and print.
With the TRIM data I have to load up this sluggish web application, add in a bunch of extra layers that aren't enabled by default, change the shading of the layers around to make it look better, create a PDF, hope that I got the scale somewhere near correct for the too-small part of the page that has a map on it and not an oversized (useless) legend and then print it out. Even after all of this I still end up with two overlapping sets of gridlines (UTM and Lat/Long) which is very confusing.
I guess there are some third-party websites that load up the TRIM data, but you still have to struggle to get something that resembles a good quality map.
Now if we could download copies of Cloverpoint's 1:20k maps we'd be all set :) |

You can just download the 1:50k mapsheets as images and view them with any image viewer software, perhaps not as powerful as a full GIS solution, but not bad. I guess if you want more control over how the data is displayed this doesn't help though. |

| I've found the NRCan maps much easier to use than the BC gov stuff. I've never really been able to figure out the basemap stuff. |

It needs a bunch of familiarity to play with it but I find trail.brijn.nu to be a good way to look at the BC Basemap data |
